Re: Or dark matter is other universes
The expansion of space means exactly that - it is not that distant objects are moving away from each other (an expansion in space), rather it is the space itself between the two objects that is getting bigger. That isn't movement in a conventional sense and not subject to the constraints relativity imposes on moving objects. If the distance between two objects is great enough the expansion of space between them can indeed be greater than the speed of light. This isn't at odds with relativity simply because the theory doesn't apply
I dimly recall hearing that postulated some time ago and it makes sense. If the speed of two galaxes (say ours and another one) are moving away from each other when the speeds are added to together and are greater than the speed of light, we'll never see them.
